2.6.11 and no sound

nukem996 · l33t Joined: 13 Nov 2003 Posts: 776

After I upgraded my laptop to the 2.6.11 kernel I realized that no sound was playing from anything(kde xmms xine or even aplay). I booted back into the 2.6.10 kernel and sound was working fine. I recompiling alsa-libs arts and xmms and nothing fixed the problem. Anyone have any clue whats wrong?

Here is my system info

IBM Thinkpad T40
Kernel: 2.6.11-ck1
Sound Card: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01) - using kernel driver snd_intel8x0.

Thanks

hmm
can you run alsamixer?

Yes and everything is turned all the way up. When I play a sound in xmms the visualization runs normally, everything runs normally but I get no sound out of the speakers or headphone jack.

I had the same problem yet the only thing I had to do was unmute a few channels in alsamixer and voila.

Some cards have a digital/analog out toggle near the end of the settings. maybe this has defaulted differently.

Could be your two iec958 settings in alsamixer aren't zero and unmuted..

I don't have time to look at this right now, I've gone back to 2.6.10 for the time being, but it appears to be a problem with alsa 1.0.8 and snd_intel8x0:

hmm that would make sense since the 2.6.11 kernel upgraded to alsa 1.0.8. Thanks for the tip ill look through google and see if I find a solution other then reverting

I'm currently using gentoo-dev-source-2.6.11-r2 on an nForce mb and using the onboard sound (snd-intel8x0) and am having no troubles whatsoever. ALSA was built into the kernel for me.

It might be related to this. Search for thinkpad on the page.

Files appear to play but there is no sound output. I see dummy card in my alsamixer and not the regular one.
Sound plays perfectly in 2.6.9 series.

Please direct me towards the solution... thanks!

I have no sound, too, since I installed the new kernel 2.6.11. The system behaves as everything will go fine except: you will her nothing. :cry:

But the hardware is ok.

I found a solution for the ThinkPad R50.

In alsamixer switch «Headphone Jack Sense» to off-state. Maybe the headphone-detection is broken or need some extra conector that is not implemented in the ThinkPad. Never mind. I'm happy now, hope, you will get your sound back, too.
